MBot retrieves the symbol and coinmarketcap.com URL for @officialmcafee's 'Coin of the Week', and automatically buys it on an exchange, currently only Bittrex. It uses OCR to extract the coin information from the image embedded in McAfee's tweet.

Add a .env file with API keys. Bittrex permissions have to be set to trade limit under Settings -> API Keys. Google credentials are needed to do OCR on the tweet using Google's Cloud Vision API. Base64 encode the keyfile into GOOGLE_API_KEY_ENCODED.

MBot emits an event with the coin symbol and tickerId when it detects a new coin of the week. tickerId can be used to construct a coinmarketcap.com URL.
Usage:
const coinEmitter = Tweets.coinEmitter;
coinEmitter.on('data', (coin) => {
console.log(coin.symbol);
console.log(coin.tickerId); // https://coinmarketcap.com/currencies/[tickerId]
});
